Brilliant thanks BrentGMATPrepNow.
So horizontal base is x coordinate here and height is y coordinate or can do by counting the columns on x,y axis which matched up?
However for the bottom right triangle's horizontal base, looking at diagram on x axis of point P, should it be length 3 here?

Which of the three triangles are you referring to?

My bad Brent BrentGMATPrepNow. For top triangle x,y coordiant is (7,4) (so base is 7 and height is 4), left triangle x,y coordiant (4,1) and right triangle x,y coordiant (3,4). Is my understanding correct? Thanks Brent

Sorry, I don't know what you mean by the coordinates (3,4).
In most cases, you aren't going to be able to straight from the coordinates to finding the areas.
Instead, you must use the coordinates to help you find the individual bases and heights of the three triangles.

For example, when it comes to the top triangle, you must use the coordinates to help you determine that the top triangle has a base of length 7, and a height of 1.
And so on

You can also find mid point of RQ and then distance from mid point to P ..
Height can be determined
Later distance RQ is base
We can solve .5* height* base
12.5

Get it thanks BrentGMATPrepNow. So for left triangel has a base of length 4, and a height of 3, right triangle has a base of length 3, and a height of 4? Hope I got it right this time. Thanks Brent
